用分光光度法比较了BTA与TTA在除盐水中对紫铜的腐 蚀动力学行为的影响，并对复合TTA与BTA+EA进行了对比.试验结果表明，与BTA+EA相比，复合TTA对铜片的成膜速度快、缓蚀效果好、缓蚀行为持久，加入复合TTA后溶液的电导率和pH值波动小.
With spectrophotometry,corrosion behavior of copper was studied in deionized water with benzotriazole (BTA) and tolytriazole (TTA) and the performance of the compound TTA was studied by comparison with BTA+EA.The experimental results show that more rapid protective film forming process,higher inhibition efficiency,more persistent inhibiting action,less fluctuations of specific conductance and pH of the solutions may be reached for the compound TTA rather than BTA+EA.
